EYEGLASS-FRAM E.

$PEC'IPICATION forming part of Letters Patent No. 348,018, dated August24, 1886.

Application filed November 9, 1885. Serial No. 182,289. (ModeLl To allwhom, it may concern:

Be it known that I, GEORGE JOHNSTON, of Detroit, county of WVayne, Stateof Michigan, have invented a new and useful Improvement inEyeglass-Frames; and I declare the following to be a full,'elear, andexact description of the same, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawings, which form a partof this specification.

My invention relates to certain new and useful improvements ineyeglass-frames, as more fully hereinafter described, and moreparticularly pointed out in the claims, the special object being toprovideimproved offset guards made adjustable at their upper ends andarranged to set back in under the eyebrows, to get a better hold uponthe nose.

As eyeglass-frames have heretofore been constructed, the spring oftenprevents the guards from setting back properly upon the nose and fromgetting a good hold. By making the guards to offset, as hereinafterdescribed, and shown in the drawings, this difficulty. is overcome, andalso without the glasses interfering with the eyelashes.

I carry out my invention as follows:

In the drawings, Figure 1 is a perspective view of a device embodying myinvention. Fig. 21's a modification,also in perspective. Fig. 3 is aseparate view of parts shown in Fig. 2.

A and A represent the glass-frames; B, the usual spring connecting saidframes, the ends ofsaid springs engaging with said frames by interveningposts at a and a.

O Orcprcsent myimprovcd guards engaged at their lower ends with theglass-frames upon intervening posts at c c, said guards being arrangedso that their upper ends are thrown rearwardly, so as to offset towardthe eyes of the wearer, permitting the guards, as before stated, to belocated under the eyebrows without being interfered with by the springB, permitting a firmer hold of the guards upon the nose, while at-thesame time the glasses are thrown forward the distance of the offset, soas to be out of the way of the eyelashes.

In Fig. 1 the upper ends of the guards are made adjustable by means ofconnecting-bars I) Z), pivotally engaged at one end upon thecorresponding end of the spring or arm W, said bars also pivotallyconnected at their opposite ends with the ends of the guards, which arepreferably turned over, as shown, to be engaged therewith. The pivotedbars I) I) make the upper ends of the guards to offset, as shown, to adesired distance, said bar being pivoted at each end, allowing a perfectand free adjustment of the upper ends of the guards to suit any user.

Instead of making the upper ends of the guards adjustable in thismanner, as shown in Fig. 1, there are a variety of ways in which thesame result can be accomplished, and I would have it understood that Idonot limit myself to any specific method ofaccomplishing this adjustability. The same may be accomplished, as shown in Fig. 2, forinstance, by engaging wit-h the ends of the spring or upon theglass-frames slotted bars a a, the outer ends of the guards beingconstructed with tenons c", to ride in theslots of said slotted bars. Bythis construction I am enabled to make eyeglass frames of superiorquality and adaptability.

IVhat I claim is- 1. The combination, with eyeglass-frames connected bya spring, of automatically-adjustable guards having their upper endsoffset from the plane of the glass-frames and spring,

'and connected therewith by intervening horizontally-pivoted barsseparate from the guards, substantially as described.

2. The combination, with eyeglass-frames connected above by a spring andprovided on theirlowcr edges with posts, of automati call yadjustableguards engaged with said posts, and intervening bars separate from theguards, and pivoted to swing in a horizontal plane for connecting theupper ends of said guards to the cyeglassframcs, substantially asdescribed.

In testimony whereof I sign this specification in the presence of twowitnesses.

ononon JO'HN'STON.
